摘　　要：背景辐射特征是目标红外辐射的重要组成部分。以典型隐身无人机为对象,分析了背景对目标红外辐射的影响机理,建立了目标红外辐射的数学模型,计算了目标在背景辐射下的红外辐射特征,并分析了背景辐射对目标红外辐射特征的影响。该研究结果将为飞行器红外探测以及红外隐身设计提供参考。Background radiation characteristic is an important part of the target infrared radiation. For the typical stealth UAV, the effect of the background radiation on target infrared radiation was theoretically analyzed, and the mathematical model of the target infrared radiation was established. Using the numerical simulation method, the target infrared radiation characteristic under the background radiation was calculated, and the effect of background radiation on the target infrared radiation characteristics was analyzed. The results provide a reference for the aircraft infrared detection and infrared stealth design.
